Patented Jan. 7, 1930 UNITED STATES PATENTIOFFICEF JOHN J. moon, or Manama, MASSACHUSETTS, assrbnon or own-Barr 'ro LEWIS J. MORGAN, or SYRACUSE, NEW YORK AUTOMOBILE nooncnncx Application filed March 27,

This invention relates to door checks, such as are used on automobile doors and has for its object a door check, which is particularly simple and compact in construction, economical of manufacture and highly-efficient and durable in use, and in which the wedge mem-' bers can be readily adjustable to receive or c'oact with a third wedge member carried on another part, usually the door, when the adjustable wedge members are carried on the door casing.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed. Figure 1 is a face view of the female unit of the door check.

Figure 2 is a face view of the male member.

Figure 3 is a rear elevation similar to Fig. 1, the cover plate being removed. Figure 4 is a sectional view on line 4-4, Fig. r

Figure 5 is a detail perspective view of the opposing pair of wedge members.

Figure dis a detail view of one of the shim plates.

Figure 7 is a fragmentary perspective view of an automobile body showing the door casing and the door provided with this door check.

This door check comprises generally a casing, which is usually attached to the door.

casing, the casing being provided with a passage 1n one wall thereof, opposing separable wed e members in the casing having spaced apar wedge faces, which are alined with the passage of the casing, a third wedge member, usually carried by the door in position to enter said passage and engage and separate the opposing wedge members, means for resisting separating movement of the opposing wedge members and means for adjusting the opposing wedge members as a unit bodilyin the casing to bring the s ace between them in proper alinement with t 1e third wedge member on the door.

1 designates the casing, which may be of any suitable form, size and construction, it usually comprising a box-like base having a passage 2 in one side thereof and 3 is a cover for the box, 1," it having a passage alined 1924. Serial No. 702,402.

with the passage 2 and also a slot 4. The-box 1 and the cover 2 are secured usually to the door casing in any .suitable manner, the box being usually set into a complemental recess in the edge of the door casing .5 and the cover 3 being secured to the box,.as by screws 6 and also to the door casing by screws 7 extending through holes 8 in a flange 9 on the cover 3,, the flange projecting from an angular wall 10 arranged at a right angle to the plate or cover 3. The flanges 9, 10 lie against the walls of a rabbet 11 formed in the edge of the door casing 5 and the screws 8 hold the casing in the recess in the door casing 5. The flange 10 is formed with a passage 12 alined with the passage 2 of the casing 1. s

13 and 14 are the pairs ofopposing wedge members arranged in a rectangular recess in the case 1 and slidably fitting the same, these members 13, 14 having opposing spaced apart wedge faces 15, 16 located with the space between said faces 15 and 16 in line with the passages 2 and 12, and also, exposed through the slot 4 in the cover 3. The wedge members are also provided with flanges 17 and 18 along at one side and one end of each of said members, the flanges of one member projecting toward the flanges of the other and serving as stops to limit the movement of the wedge members 13 and 14 toward each other. Suitable resilient means resist separation of the wedge members 14 and 13, when the wedge member associated withthe door enters between the wedge members 13 and 14.

This resilient means, as here shown, comprises rubber blocks 19 arranged in recesses 20 in the rear sides of the wedge members 13 and 14, these blocks substantially fitting the casing, that is, the blocks are substantially the same width as the recess in the box or casing 1.

The means for adjusting the wedge mem- -hers as a unit or bodil raising or lowering them in order to aline t e space between them the wedge member associated with the door, comprises shim plates 21 insertable between the blocks 19 and the upper and lower end walls of the recesses of the box 1. Obviously, by removing one of the shim plates .behind one of the wedge members 13 or '14 and inserting it behind the other wedge member, the

wedge members will be moved bodil in one direction or the other, thus bringing t e space between the members higher or lower, asdesired, in order to receive the wedge member on the door.

23 designates the wedge member, which is mounted on the edge of the door 24, this wedge member 23 usually carried on a base plate 25,

. in the door casing and the doors closed to de;

termine whether or not the wedge member 23 fits or mates properly with the opposing wedge members 13, 14, and if these parts do not fit or mate properly, the portion of the wedge members 13, 14 can be readily raised and lowered by shifting the shim plates 21. The cover 3 is then permanently secured in position. If at any time, an adjustment is required, due to permanent compression of the rubber buffer blocks, additional wedge plates can be inserted to correct the defect.

This door check is particularly advantageous in that it consists in afew simple compactly arranged parts which are economical in manufacture and also in that it can be readily adjusted to correct variations that are bound to occur in quantity manufacturing and further in that any variations that de velop by use of the device can be readily corrected.

Although the device acts as a buffer to prevent slamming of the door and is for convenience called a door check, it also acts to support the door at its free edge. when closed, and to guide the door to its closed position.

What I claim is:

1-. A door check comprising a casing having a passage in a wall thereof, opposing separable wedge members arranged in the casing and having spaced apart faces, the space between said faces being in line with said passage and such passage being of greater width than the space between the wedge members, means for shifting the wedge members as a unit relatively to said passage, and a third wedge member movable into and out of the passage and coacting with the former wedge members, said means comprising shims arranged on opposite sides of the wedge members.

2. In a' door check, the combination of a casing having a passage in a wall thereof. a pair of opposing separable wedge members having faces spaced apart. the space between such faces being alined with the passage and the passage being of greater width than said 1,742,eao

space, resilient means on opposite sides of the wedge members, means for shifting the prising shims arranged on opposite sides of the wedge members.

3. In a door check, the combination of a casing having a passage in a wall thereof, a pair of opposing separable wedge members having faces spaced apart, the space between such faces being alined with the passage and the passage being of greater width than said space, resilient means on op osite sides of the wedge members, means for shifting the wedge members as a unit relatively to such passage, comprising shims arranged between the resilient means and the casin and a third wedge member movable into t e passage into engagement with the opposing wedge members. o

4. A door check comprising a casing having a passage in the wall thereof, a pair of op osing separable .wedge members arrange in the casing and having faces spaced apart, the wedge members being shiftable toward and from each other, the space between such faces being alined with said passage, and the wedge members also having stops extending toward each other for limiting the movement of the wedge members toward each other, a resilient backing for each wedge member and a third wedge member movable through the passage into engagement with the pair of wedge members. v

5. In a door check, the combination of a casing having a passage in a wall thereof, a pair of opposing separable wedge members in the casing and having faces spaced apart, the wedge membersbeing shiftable toward and fromeach other, the space between said faces being alined with said passage and a resilient backing for the wedge members comprising a block extending substantially the width of the wedge members and fitting the casing, and a third wedge member .movable through the passage between the pair of wedge members.

casing having a passage in a wall thereof, a pair of opposing separable wedge members in the casing and having faces spaced apart, the space between said faces bein alined with said passage and a resilient bac ing for each wedge member comprising a block extending substantially t e width of the wedge members and fitting the casing and shim plates arranged behind each backing, and a third wedge member movable through the passage into engagement with the opposing wedge members.

7. A door check comprising a casing having 6. In a door check, the combination of a a passage in one wall thereof, a pair of wedge members in the casing having spaced apart. faces, the space between the faces being alined' with said passage and the wedge members having sockets on their rear faces, resilient wedge blocks fitted in the sockets, the pits sage being of greater width than the space between the wedge members,'and shim plates arranged between said blocks and the casing. In testimony whereof, I have hereunto signed my name, at Merrimac, in the county of Essex and State of Massachusetts, this 20th day of March, 1924.
